An athlete decided to embed a "lucky loonie" in the ice before his hockey game. The mass of the mostly nickel coin is 6.27 g and its specific heat is 0.440 J/g·ºC. To what temperature must he heat the coin so that its volume of 1.08 cm3 displaces an equivalent volume of water on the surface of the ice? Assume the temperature of the ice is 0.000 ºC.
